ABSTRACT
We present a parametric, computational model of head-eye coordination that can be used in the animation of directed gaze shifts for virtual characters. The model is based on research in human neurophysiology. It incorporates control parameters that allow for adapting gaze shifts to the characteristics of the environment, the gaze targets, and the idiosyncratic behavioral attributes of the virtual character. A user study confirms that the model communicates gaze targets as effectively as real humans do, while being preferred subjectively to state-of-the-art models.

Eye, Head and Torso Coordination During Gaze Shifts in Virtual Reality
Humans perform gaze shifts naturally through a combination of eye, head and body movements. Although gaze has been long studied as input modality for interaction, this has previously ignored the coordination of the eyes, head and body. This article ...
